As an addendum to my previous post, when I found the TPMS screen I was sitting in my driveway with the car not running. Once I started the car, I got a message on that screen that said "tire pressure will show once car begins moving". Sure enough, once I began driving, the tire pressures began appearing, and all 4 were showing within about a quarter mile. They came up somewhat slowly, one at a time. The surprising thing was that 2 of the tires showed at 46 pounds, one at 47, and one at 48! They are rated at 44 pounds max. They were basically cold, so it wasn't a case of heating up after driving for awhile. The dealer apparently set them a little high in their delivery prep (car is new - had only about 200 miles on it at the time). When I got back home, I used my gauge to set each of them to 44 pounds, and then checked them with the TPMS reading on the dash, and they each showed exactly 44 pounds - so it appears the TPMS reading is pretty reliable. I guess learning many of the fine points of the car are sort of trial and error, as none of this was clearly shown in the manual.
